GOVERNOR Filed Sept. 28, 1937 2 Sheets-Sheet 2 Inventor AttorneysPatented Aug. 9, 1938 UNITED STATES PATENT OFFICE 2 Claims.

This invention appertains to new and useful improvements in governorsfor wind motors such as windmills and the like.

The principal object of the invention is to provide a governor forautomatically regulating the speed of the wind driven propeller.

Another important object of the invention is to provide a governorstructure which will be simpleacting and substantially fool-proof.

Other important objects and advantages of the invention will becomeapparent to the reader of the following specification.

In the drawings:-

Figure 1 represents a side elevational view of the assembly.

Fig. 2- is a front elevational View of the propeller and governor.

Fig. 3 is a fragmentary longitudinal sectional View showing thegovernor.

Fig. 4 is a fragmentary plan view of one of the weight members.

Fig. 5 is a fragmentary perspective view of one of the weight members.

Fig. 6 is a cross sectional view, taken substantially on the line 6-45of Fig. 3.

Referring to the drawings, wherein like num erals designate like parts,it can be seen that numeral 5 denotes the usual skeleton tower forsupporting the generator t which is driven by the wind propeller I, thepropeller being located on the shaft 8.

As is clearly shown in Fig. 2, the propeller I is provided with the hub9 and to this hub is secured the governor mechanism generally re- Jferred to by numeral I0.

This governor mechanism consists of the elongated barrel I I providedwith ball bearing mounts I2 in the opposite ends thereof and throughthese ball bearing mounts are disposed the cylindricalshaped weightmembers I3l3.

The outer ends of these weight members I3 are bifurcated as at It forreceiving the broad paddle blades I5 which are secured to the bifurcatedportion by suitable securing means IS.

The inner ends of these weight members I 3 are reduced as denoted bynumeral I1 and then twisted to a screw form I8. The barrel II adjacenteach end thereof is provided with a pair of closely spaced pins I9I9disposed therethrough transversely and between each pair of pins I8I9 isdisposed the adjacent screw form I8. 7

At the intermediate portion of the barrel I I an anchoring pin 20 islocated and from this pin in opposite directions extend the coiledextensible springs 2I2I, each of which connects at its outer end to theadjacent end of the corresponding screw form I8 as is clearly shown inFig. 3.

On the inner end portion of each of the weight members I3, that isinwardly of its screw form I8, is located a stop pin 22 between whichand the corresponding ball bearing mount I2 a coiled compressible spring23 is located and in convoluting position on the corresponding weightmember l3.

It can now be seen that as the barrel II is rotated by the propeller I,and speed increases, the weight members I3 move outwardly due tocentrifugal force and as they do so the same rotate due to thedisposition of the screw forms I8 between the pins I9-I9. This actioncauses rotation of the blade-like paddles I5 so that they will move orrotate from a position on a plane with the propeller I to the otherextreme as shown in Figs. 1 and 2, that is at right angles to the planeof the propeller l and this, of course, acts as a retarding means forthe propeller.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is Y 1. Retardingmeans for rotary structures comprising a barrel secured toa rotarystructure toproject laterally therefrom, a shaft longitudinally disposedin the barrel and projecting at one end from the free end of the barreland being slidably disposed therein, a paddle on the outer end of theshaft, said shaft provided with a spiral formation at its inner end, ananchor in the barrel, an extensible coiled spring in the barrel havingone end connected to the anchor and its opposite end to the spiralformation, a coiled compressible spring on the shaft having one endconnected to the inner end portion of the shaft and its outer endabutting the adjacent end portion of the barrel.

2. Retarding means for rotary structures comprising a barrel secured toa rotary structure to project laterally therefrom, a shaftlongitudinally extending from the outer end of the barrel and journallysupported therein, a paddle on the outer end of the shaft, said shaftbeing longitudinally slidable in response to centrifugal force, springmeans for retracting the shaft when relieved of centrifugal force, andmeans for causing rotation of the shaft as it slides in the barrel, saidmeans for causing rotation of the shaft consisting of a pair of closelyspaced pin members disposed across the interior of the barrel, saidmeans for causing rotation of the shaft further including a spiralformation on the inner end of the shaft ridably disposed between the pinmembers.
